A/N: Sorry it's been awhile. New baby and all, really have struggled with time. That and I just wasn't happy with the beginning here. I changed it about half a million times before deciding on this. I struggled so much with keeping the characters IC yet allowing them to get all schmoopy and lovey. It was a challenge and I still worry if I pulled it off. Please, let me know! Thank you SO much to all the reviewers. You guys keep me sane when I'm up at three in the morning feeding. Here is the next part... we are onto the last 10k words... wow, is it really almost over? It's been a blast! So, sit back and enjoy!

Part Four A

Dean didn't sleep that night. He couldn't. There were way too many thoughts bouncing around in his head to let him rest.

His eyes strayed to the slumbering angel next to him. Cas's words reverberated in his mind. Had he really said what Dean thought he said? That he had feelings for him? It's what it had sounded like. That complicated things to the nth degree, but… a small part of Dean didn't care.

He tried to think of what the hell they would do with these… feelings between them. Cas was an angel; he had responsibilities in Heaven. Granted, his friend had been spending a good portion of his time on earth helping out him and Sam, so it wasn't like Dean was worried that he wouldn't be able to see Cas all that much. On the other hand, well, Cas was a freaking angel! That was not a good premise for a relationship. Of course, neither was being a hunter, truth be told. One night stands, yeah sure, but relationships? Not so much.

Dean sighed and turned over, eyes straying to the knobs of Cas's spine. He could see the bruises from his tumble with Sam in the pale light of dawn. They were a stark reminder that Cas might be an angel, but at the moment, he was very, very human. Which also meant the other man would probably be suffering from one hell of a hangover when he woke up. That was one thing Dean could take care of.

The hunter quietly got up from the bed and walked into the bathroom. He grabbed two aspirin and filled a plastic cup with water then went back out into the main room. He walked over to the bedside table closest to Cas and set the cup and the pills down so they would be easily accessible when his friend woke up. Then he crawled back into the bed, snuggling (though Dean would never admit that's what he was doing) up to Cas from behind, spooning easily into the shorter man's body.

His mind still refused to calm down so he let his eyes wander to the back door that led out to their small deck. He could just see the sun rising, the entire world bathed in oranges, pinks, golds, all the colors that indicated a new day was being born. He felt Cas shift in his light embrace, a soft moan leaving his friend's throat.

"Hey, you okay?" he asked quietly.

"No," Cas voice came out rough and gravely. It sent a shiver down Dean's body and caused Dean's dick to stir in his boxers. "I think I might be dying."

Dean snorted. He didn't mean to, he knew the poor guy wasn't used to dealing with hangovers, but really? A little too dramatic.

"Dude, you aren't dying. It's a hangover. You have had one of those before," he told Cas, keeping his voice low so as not to irritate the angel's poor head. He left his arm draped over Cas's waist, wondering if his friend had even noticed it yet. "Look, I got you some meds already. Trust me, take the two aspirin and drink the water, it'll help."

Cas reached over and gingerly took the two pills, pulling himself out of Dean's reach. He quickly downed the medicine and drank the water then set the empty cup back down on the bedside table.

"How long does it take them to work?" Cas asked miserably. "I feel like I am about to be sick."

"Half an hour or so," he replied. Cas moaned. "And if you're gonna puke, head to the bathroom, but it's probably just the feeling, all part of the joy of too much alcohol. Just relax, it'll go by quick, promise." The angel started to relax back into Dean but tensed at the last second. It seemed that Cas finally realized the position they were in. That or he remembered his words from last night. He started to pull away but Dean just tightened his hold.

"Dean…" Cas warned.

"Are you about to puke?" he asked.

"No," Cas answered, body still tense and straining towards the outside edge of the bed.

"Then your ass is staying right here."

"Dean," Cas started once more but Dean cut him off before he could start babbling excuses or worse, apologies.

"Cas? Shut up. We'll talk when your head has stopped pounding. And don't start thinking you know what's going on in my brain, because that's getting old."

The angel turned his head to face Dean, confusion evident in his eyes.

"Sleep now, talk later," Dean ordered before closing his eyes. He was tired and he finally felt like he might be able to slip into sleep if Cas would just cooperate with him.

"Alright," Cas finally whispered, settling his head back down onto the pillow. His body slowly relaxed into Dean's hold. The hunter closed his eyes and finally dozed off.

When Dean woke up, the sun had fully risen and was shining brightly through the French doors that led out the back of their cabin. Cas had turned over some time while they slept and now was facing Dean, head nestled under his chin, breath tickling his neck. He still had his arm around the angel and one leg had found its way in between Cas's. It should probably worry Dean how much he, well, wasn't freaking out about this.

Cas had made a confession last night, granted it was a very drunken confession, but it was the truth nonetheless and it gave Dean the clarity and courage to let his friend know exactly how he felt. He didn't know what the hell they were going to do with all these feelings, but it was about damn time they put them on the table. His brother would be shitting himself if he knew all the thoughts that were going through Dean's head. After this morning, Dean was swearing off chick flick moments again because he had seriously met his quota on mushiness with this.

Cas stirred against him. His top leg moved up Dean's thigh bringing their hips closer together. It did nothing to help his morning erection. He watched Cas's eyelids flutter open, glassy blue eyes met his in confusion before a deep blush colored the angel's face.

Cas started to pull back but Dean tightened his arm, holding his friend where he was.

"We need to talk."

Cas lowered his eyes, shame flashing across his features.

"I'm-"

"Cas, shut up. My turn," Dean interrupted. Cas just nodded, still refusing to meet Dean's eyes. "Listen, there's something I should probably tell you, something I tried to tell you the other day before you spouted off that nice little speech about meaningless sex."

Cas shifted. Dean could tell he was uncomfortable but too bad. He was going to get this out one way or another.

"You thought you knew what I was going to say, and granted, my… reputation when it comes to one night stands isn't that great, but… you should have given me a chance, Cas. You can't read my mind."

Cas's eyes shot up to meet his finally. They were confused but Dean could see a hint of anger in there as well.

"No, maybe I can't, but I know you, Dean."

"Yeah, you do, but apparently not as well as you thought. Hell, when it comes to this, I don't even know me. Because, seriously, Cas, this is so far out of the ballpark for me."

"What are you talking about?"

"I'm talking about the… fuck, the way I feel. About you."

Cas's eyes widened as he stared at Dean. The hunter waited for the other man to say something but Cas's mouth remained tightly shut.

"When you started talking about how you didn't have any feelings to hurt, how you completely understood that what we did meant nothing and that was totally fine, well, it sorta threw me for a loop. For the first time in a long time, it had actually meant something and when I got my head out of my ass long enough to admit it, here you were telling me 'Thanks for the fuck, see ya later.' I'm not used to that. Didn't realize how unpleasant it was to be on the other end of that."

"I… Dean, what are you… I thought…" Cas took a deep breath before trying again. "I thought I was making it easier on you," he admitted. "I was sure that you merely needed release and I was the closest willing person."

"Yeah, I kinda figured that after your little confession last night." Cas scowled.

"Alcohol is evil."

"No, it's not. It just makes one hell of a truth serum. Seriously, Cas, I… what you said, I feel the same way. Especially the whole, 'pain in my ass' part," he told his friend, hoping to break the tension a bit.

Cas searched his eyes but Dean had no idea what he was looking for.

"I'm not sure what to do with these feelings," Cas finally admitted.

"Me either. I mean neither of our lives are exactly cut out for this shit."

"I have a responsibility to Heaven," Cas whispered.

"I gotta be there for Sammy, out on the road, hunting, it's my life. I tried the apple pie thing, it wasn't me, and it didn't work."

Dean and Cas lay there for a minute in silence, eyes glued together.

"Then, perhaps we should enjoy the time we have here," Cas whispered, moving his body closer to Dean's. The hunter raised an eyebrow at that. The angel pressed his lips hesitantly to Dean's. Dean kissed him back enthusiastically, slowly exploring every inch of Cas's mouth as if it was the first time. In a way, it was. He was seeing his angel, his friend in a whole different light. He wasn't hiding any more and that gave everything a different feel. Cas pulled back first, breaking the kiss.

"We're going to miss our group session," Cas said, eyeing the clock behind Dean.

"Forget about it. I'd much rather be here with you. We'll make up something, or hell, tell her we spent the morning 'rekindling our romance' or some shit like that. Hannah'll eat it up."

"I like that idea. Dean… there's something I've been curious about, something I've wanted to try," Cas spoke hesitantly.

"What's that?"

"Do you trust me?"

"With my life," Dean repeated his words from the day before with a smirk.

"And you'll keep in mind that I have no idea what I'm doing?"

"Honestly, Cas, when it comes to this," Dean waved his hands around the room, "I don't know what the fuck I'm doing either. I haven't exactly done this shit with a guy before."

"Then, no judging, on either end."

"Sounds good. Now, what did you want to try?"

Instead of answering, Cas moved his hands down and tugged Dean's boxers down his hips, freeing his semi-hard cock. Dean kicked them the rest of the way off. The hunter smirked. He liked where this was going. Cas met his eyes once more and Dean could see the slightest hesitancy in them before the angel slithered down the bed, stopping when his face was even with Dean's hips. He sucked in a breath as Cas leaned closer to him, eyes trained on his cock where it lay against his stomach, filled with blood. He was pretty damn sure about what was going to happen and his brain was slowly shutting down.

Cas carefully gripped Dean's dick in one hand. The angel flicked his tongue out and ran it along the tip causing Dean to let loose a moan. The warm, wetness of Cas's tongue was fleeting, barely enough to call a tease. Cas leaned back in, this time taking the whole tip into his mouth and letting his tongue trace the sensitive area just under the head. Dean fought against the instinct to grab the dark head and shove him further down.

After an agonizing few seconds, Cas finally sunk down on Dean's dick. He slowly began to bob up and down, letting his tongue map out every inch of hardness. Every time he'd come up, his tongue would flick over the tip, stabbing at the slit in a way that was driving Dean nuts.

It was a sloppy blow job, there wasn't much of a rhythm, Cas didn't use his hand enough, but at the same time, the pure innocence and wonder Cas showed was hot enough to have Dean on the edge in an embarrassingly short time. Dean reached down and cupped his hand around the one Cas had on his cock and showed the angel how to pump with the movement of his mouth. Once the other man caught on, the pleasure surged. Dean felt his balls draw up tight and knew he was about to blow.

"Cas… uh, you might want to move. I'm about to…" Cas seemed to understand what Dean was having trouble getting out. He pulled off with a pop but continued to move his hand over the rigid flesh. A handful of strokes later and Dean was pumping out his release. He closed his eyes and let his head fall onto the pillow as his body trembled in aftershocks.

It took him a few minutes to remember that reciprocation was the only polite thing to do, that and he was dying to see Cas fall apart again. Only, he really wasn't sure he was ready to offer the angel the same treatment. Did that make him a coward?

Dean pushed those thoughts away as he pulled Cas in to capture his lips again. He pushed Cas's own boxers down and off, using his foot to move them somewhere near the end of the bed. He slid one muscled thigh in between the angel's legs as he let his hands slip down to grab Cas's ass. He pulled their hips flush together as he devoured the other man's mouth. He nipped at Cas's bottom lip with his teeth then soothed it with laps of his tongue. Dean rolled his hips against the angels and felt the hard length of Cas's erection trail across the jut of his hip, a warm wetness trailing where it slid.

Cas's breath hitched, his own hips thrusting against Dean. The hunter smiled into Cas's mouth. Dean let his hands move over the angel's ass, hips, thighs, exploring the area he's not had much of a chance to see yet. He thought for a moment about straying to that forbidden place, the most intimate place. He wondered what Cas would do. Was that something the angel wanted? Did that thought turn him on?

Curiosity won over and Dean let one hand move to the cleft of his ass. He let one finger slide down in between the cheeks to land on the furled hole hidden there. Cas gasped as his hips stuttered. Dean put the slightest amount of pressure there and Cas hissed as he came. The angel's whole body was vibrating as he pumped his load onto the hunter's hip. Dean was drunk on the powerful feeling he got from bringing the angel to that point. He moved his hands up until he was embracing Cas, holding him close as he came down from his orgasm induced high.

"You okay?" he asked, voice rough and wrecked.

"Yes. That was… I…" Cas's voice trailed off as he laid his head down on Dean's shoulder.

"Yeah, it was," Dean agreed, pretty sure he knew what Cas was trying to say. He pulled the angel even closer as he closed his eyes and let sleep take him, forgetting about the mess between them and the wet spot on the bed.

When Dean woke up the next time, it was to an empty, cold bed. His heart immediately dropped to his stomach. He knew it had been too good to be true. He honestly thought he would be the first to freak out, but apparently he was wrong. He sighed.

"Sam has called twice. I didn't want to wake you, so I told him we would meet with him before lunch," Cas spoke up from the door of the bathroom. Dean glanced over in surprise.

Cas was dressed in a light blue t-shirt and a faded pair of jeans. His hair still looked damp so he must have taken a shower. He didn't look like he was freaking out.

"What time is it?" Dean asked.

"Eleven thirty. Sam should be here any minute, so you might want to put some clothes on." Dean nodded and watched as Cas wandered over to the refrigerator, probably in search of another Mt. Dew. The angel looked rested and calm, it didn't seem like anything was bothering him, but he really needed to be sure.

"Hey, Cas. Are we… okay?" he asked hesitantly. Cas turned to look at him, a small smile on his face.

"Yes, Dean, we're okay," he answered.

"Good," Dean responded as he made his way from the bed into the bathroom.

"Dean? Don't forget your clothes this time. Your brother probably would prefer you put the clothes on before leaving the bathroom." Dean's laughter bubbled out with a snort. Yeah, Sam probably would prefer to not get a free peep show.

"Good idea. Wouldn't want Sammy to need to dig out the brain bleach." Cas's face screwed up in confusion. Dean laughed again. "You have so much to learn, Cas." The angel shrugged.

"Good thing I have you to teach me."
